Experimental data and analysis of performances of dual-type temperature probes

Experimental data, VBA software, and data analysis resulted from an investigation of the performances of prototypes of dual-type temperature probes, that were used for testing the new concept of dual-type thermometers. Dual-type thermometers enable in-situ determination of thermocouple drift. The basic idea behind the concept is that thermocouple drift can be continuously monitored in situ by placing an additional and different temperature sensor in close proximity. The essential requirement for this additional sensor is that it experiences a drift that is lower than the drift of the monitored thermocouple. A drift of a thermocouple can be determined by an algorithm that monitors, and over time compares, the differences in its temperature readings and the readings of an additional (reference) sensor.
